Hi, I'm trying to use a USB-serial converter with an external (RS232), hardware modem. The converter is a no-name, Asian brand with the Prolific 2303 chipset. I'm trying to get it to work with the pl2303 driver. Using the in-kernel version (2.6.21, built with make-kpkg from the Debian source package), the driver builds and loads and creates /dev/ttyUSB0, but communication with the modem doesn't work (I have used this US Robotics Sportster successfully on a different system that has an actual serial port). The included driver CD contains what seems to be an older version of pl2303, which I haven't yet tried. This site [0] suggests that some apparent 2303 are really 2303X and need a patch to work, but I tried the patch against my 2.6.21 sources, and patching failed. The site seems old; perhaps the code has been integrated into the mainline kernel? The CD suggests that it may indeed be a 2303X, but it isn't entirely clear. Does anyone have any experience with these things, or any suggestions about getting them to work?
A bit more detail: when I talk to the modem with minicom or wvdial, the commands (e.g. ATI0) are echoed back, but I get no response from the modem, the status lights don't change (the CS light is the only one lit, and it remains so) and nothing else happens. When the modem isn't there (or is off) then I get nothing at all, not even the echo (which I believe is correct :).
